ADU Builder in Colorado Springs
Custom accessory dwelling units, detached casitas, in-law suites, and garage ADUs, designed and built under one roof.
An accessory dwelling unit (ADU) is a self-contained second home on your property: a detached casita, an attached in-law suite, or a unit above a garage. Stewart Remodel Design Build designs and builds custom ADUs across Colorado Springs, handling zoning, permits, and construction under one roof, as a design-build firm since 1999 with 2,000+ completed projects.

As a true design-build firm since 1999, we handle every step under one roof, zoning and design, utilities, and construction, whether you want a detached casita, an attached in-law suite, or a unit above a detached garage. With more than 2,000 completed projects and a 4.8-star Google rating, we build ADUs that work as rentals, guest houses, and family suites for years to come.
Detached ADUs & Casitas
A standalone second home in your backyard, with its own entrance, kitchen, and bath. We design it to match your main home and make the most of your lot, whether it is for rental income, guests, or family.
- Full kitchen & bathroom
- Private entrance
- Matched to your home’s style
- 400 to 1,000+ sq ft
Attached Suites & In-Law Additions
A private suite added onto your existing home, ideal for aging parents or grown kids who want independence while staying close. We blend the rooflines and finishes so the addition looks original to the house.
- Private entrance & bath
- Kitchenette or full kitchen
- Seamless, matched rooflines
- Aging-in-place options
Garage ADUs & Conversions
Turn a garage into living space, or build a new unit above one. A great way to add a full ADU on a smaller lot. We also pair ADUs with a new detached garage when you want both the parking and the living space.
- Living space above a garage
- Garage-to-ADU conversions
- Maximizes a smaller lot
- Pairs with a new detached garage
Design, Zoning & Permitting
ADUs come with their own zoning, setback, and utility rules. Because we design and build under one roof, we review your lot’s requirements up front and carry the approvals for you, so there are no surprises mid-project.
- Colorado Springs & El Paso County ADU rules
- Zoning & setback review
- Utility, sewer & septic planning
- One accountable design-build team
Detached ADU vs. Attached Suite
The two most common ways to add an ADU. Here is how a standalone unit compares to a suite attached to your home, so you can pick the right fit for your lot and goals.
| Detached ADU / Casita | Attached Suite / Addition | |
|---|---|---|
| What it is | A standalone building | Built onto your existing home |
| Privacy & rental appeal | Highest | Moderate |
| Typical footprint | 400 to 1,000+ sq ft | Sized to your home |
| Shares walls with your home? | No | Yes |
| Best for | Rental income, guest house, multigenerational living | Aging parents or a private suite close by |

Learn moreADU FAQs (Colorado Springs)
An accessory dwelling unit is a smaller, self-contained home on the same lot as a main house. It has its own kitchen, bathroom, and entrance. Common types include a detached backyard casita, an attached in-law suite, and a unit above a garage. ADUs are used for rental income, guests, and multigenerational living.
Yes, Colorado Springs and El Paso County allow accessory dwelling units under specific zoning, lot-size, and setback rules that depend on your property. Rather than guess, Stewart reviews your lot’s zoning up front during a free consultation and handles the approvals in El Paso, Teller, and Douglas counties, including through the Pikes Peak Regional Building Department.
Cost depends on the ADU type (detached, attached, or garage), its size, and finishes, plus any utility or sewer work your lot needs. Instead of a one-size-fits-all number, we walk your property during a free consultation and give you a detailed, transparent estimate built around your actual project.
A custom ADU typically takes about four to seven months from design through final inspection, depending on type, size, and permitting. Detached units and garage builds usually take longer than an attached suite. You receive a clear schedule before construction begins and updates throughout.
In most cases, yes, ADUs are commonly used as long-term rentals, and rental income is one of the top reasons homeowners build them. Whether short-term rental is allowed depends on your specific zoning and any HOA rules, which Stewart reviews for your property before you commit to a design.
A detached ADU offers the most privacy and rental appeal and works well as a standalone guest house or income unit. An attached suite is usually more affordable and is ideal for keeping aging parents or family close while giving them independence. We help you weigh your lot, budget, and goals during the consultation.
Yes. Stewart builds living space above a new or existing garage and converts garages into full ADUs. This is a smart way to add an ADU on a smaller lot. If you want both parking and living space, we also build a new detached garage with a unit above it.
Yes. An ADU adds usable square footage, potential rental income, and flexibility for multigenerational living, all of which increase a property’s value and appeal. In a tight housing market like Colorado Springs, a well-built ADU is a strong, lasting investment.
